To all whom it may concern:

Be it known that I, JOHN M. OoNnoY, residing at Allegheny, in the countyof Allegheny and State of Pennsylvania, a citizen of the United States,have invented or discovered certain new and useful Improvements inFrames for Mirrors, (to, of which improvement the following is aspecification.

The invention described herein relates to certain improvements insecuring mirrors, etc., in frames, and has for its object a constructionwhereby the glass may be rigidly fastened in the frame, the fasteningmeans being constructed in such manner that, while firmly clamping theglass, there is no liability of injury to the same.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a back elevation of a frame having the glass secured thereinin accordance with my invention; Fig. 2 is an enlarged detail Viewshowing the fastening devices; Fig. 3 is a sectional view on a planeindicated by the line IIIIII Fig. 2; Figs. 4 and 5 are respectivedetailed views of parts of the fastener.

In the practice of my invention the side bars 1 of the frame are securedtogether by a cross bar 2, which in the construction shown has its outerends bent up and riveted to the side bars in such manner as to permit ofthe rotation of the cross-bar. Slides 3 provided on one side withgrooves for the reception of the cross bar, are mounted on the latter insuch manner, that when moved towards each other along the cross bar,lugs 4 will grip the edges of the glass 5. At their inner ends theseslides are provided with upwardly projecting loops 6 for the receptionof the ends of braces or struts 7. The outer ends of these struts areprovided with suitable means for interlocking with the cross bar orother stationary part of the frame. In the construction shown the endsof the struts are notched to receive the lugs on the ends of the crossbar. These struts are made of such a length relative to the position ofthe'slots of the slides, when the latter are shifted to grip the glass,as to require an upward bowing or bending of the struts as indicated inFigs. 3 and 4 to permit of the insertion of one end of the struts intothe loops 8, when the opposite ends are in engagement with thecross-bar. After the slides have been moved along so that the lugs orears thereon will engage the edges of the glass, the struts are placedin position, one end passing in the slots of the slides and the otherengaging a stationary part of the frame, the central portion of thestruts are thrust down forming a reverse curve or bend, as shown in Fig.3, in the strut and locking the same in position. The downward forcingor bending of the struts will force the slides inwardly and firmly clampthe glass in position.

The strut is made of flexible material so that it will take a set whenbent to lock the slides, but the two bends or arches a formed by bendingthe strut will afford some slight resilience which will prevent the lugsof the slides from being pressed with sufficient force against the edgeof the glass to injure the latter.

The slides are made of sheet metal, the groove for the reception of thecross bar being stamped therein. The loops 8 are formed by slitting thegrooved portion of the slides adjacentto their inner ends and slightlystretching the portions outside of the slits.

The sides hold the glass against the cross-bar and the struts or lockingpieces and slides hold the glass'from movement along the cross-bar, andcentral between the sides of the frame.

I claim herein as my invention:

1. As a means for securing glass in frames the combination of a crossbarsecured to the sides of the frame, slides provided with lugs adapted toengage the edges of the glass and serving to hold the glass on thecross-bar and locking pieces interposed between stationary portions ofthe frame and shoulders on the slides whereby the lugs on the slides areheld in engagement with the glass.

2. As a means for securing glass in frames, the combina tion of slidesbearing on one side of the glass and pro vidcd with lugs adapted toengage the edges of the glass, :1 cross-bar secured to the sides of theframe and adapted to pass between the glass and the slides, lockingpieces interposed between portions of the cross bar and shoulders on theslides.

' 3. As a means for securing glass in frames, the combination of slidesbearing on one side of the glass, and pro vided with lugs adapted toengage the edges ofthe glass and having shoulders thereon, a cross-barsecured to the sides of the frame and adapted to pass between the glassand the slides and flexible locking pieces of lengths greater than thedistances between shoulders on the slides and portions of the cross-bar,when the logs of the slides are in engagement with the glass, saidlocking pieces being bent between their ends'to lock the slides andlocking pieces in position.

In testimony whereof, I have. hereunto set my hand.

JOHN M. CONROY.
